Operation mode setting
Following to power connection, Compressor Cooler starts operation in the each setting mode.
Factory setting for the setting temperature is 35
℃
with 5
℃
differential, which means the compressor starts for
cooling when the temperature inside the enclosure reached 35
℃
and stops at 30
℃
.
Four operation modes of continuous run and three different energy saving mode are available.
Pay attention to the following matters in every operation mode.
・
In case the internal temperature exceeds the high temperature alarm setting when power is turned on, the alarm lamp lights
by the setting of AS and Ao according to the assignment table of alarm output terminals described in page 38.
・
Cooling operation will not start for a certain period of time (initial setting: 3 min) after cooling operation has stopped even if the
internal temperature goes up to the set temperature.
(1)
Continuous run
Cooling operation starts at the set internal temperature and the external fan and the compressor will stop at the
set cooling operation stop temperature. The internal fan does not stop. The values in the ( ) show the default
setting.
(2)
Energy-saving mode 1

Note
・
For protection of the refrigerant circuit, the internal fan will not stop for 5 minutes after cooling operation has
stopped.
・
The internal fan runs continuously when the internal temperature exceeds the cooling operation stop
temperature.ly when the internal temperature exceeds the cooling operation stop temperature
